Sub-50 nm perovskite-type tantalum-based oxynitride single crystals with enhanced photoactivity for water splitting

open access: yesNature Communications, 2023
A long-standing trade-off exists between improving crystallinity and minimizing particle size in the synthesis of perovskite-type transition-metal oxynitride photocatalysts via the thermal nitridation of commonly used metal oxide and carbonate precursors.

SUPRA HOMEOMORPHISM IN SUPRA TOPOLOGICAL ORDERED SPACES [PDF]

open access: yesFacta Universitatis, Series: Mathematics and Informatics, 2017
The purpose of this paper is to introduce the concepts of x-supra continuous (open, closed, homeomorphism) maps in supra topological ordered spaces for x ∈ {I,D,B}. We study the relationship among these types with the help of examples and investigate the equivalent conditions for each concept.

Highly oxidation-resistant graphene-based porous carbon as a metal catalyst support

open access: yesCarbon Trends, 2021
Porous graphene (PG) prepared from reduction and KOH activation of graphene oxide was heat-treated under argon atmosphere to obtain a partially graphitized porous carbon with high oxidation resistance. Transmission electron microscopy, Raman spectroscopy,

Dissecting the Environmental Consequences of Bacillus thuringiensis Application for Natural Ecosystems

open access: yesToxins, 2021
Bacillus thuringiensis (Bt), a natural pathogen of different invertebrates, primarily insects, is widely used as a biological control agent. While Bt-based preparations are claimed to be safe for non-target organisms due to the immense host specificity ...

Sequential cocatalyst decoration on BaTaO2N towards highly-active Z-scheme water splitting

open access: yesNature Communications, 2021
Activation of narrow-bandgap photocatalysts holds key to applicable solar-to-hydrogen energy conversion. Here, the authors demonstrate effective sequential cocatalyst decoration for such narrow-bandgap photocatalysts to realise highly-efficient hydrogen ...

The man, the plant, and the insect: shooting host specificity determinants in Serratia marcescens pangenome

open access: yesFrontiers in Microbiology, 2023
IntroductionSerratia marcescens is most commonly known as an opportunistic pathogen causing nosocomial infections. It, however, was shown to infect a wide range of hosts apart from vertebrates such as insects or plants as well, being either pathogenic or

Attachment of composite porous supra-particles to air–water and oil–water interfaces: theory and experiment [PDF]

open access: yes, 2016
We developed and tested a theoretical model for the attachment of fluid-infused porous supra-particles to a fluid–liquid interface. We considered the wetting behaviour of agglomerated clusters of particles, typical of powdered materials dispersed in a ...

Combined supra/infratentorial approach to tentorial meningiomas Abordagem combinada supra e infratentorial aos meningiomas tentoriais

open access: yesArquivos de Neuro-Psiquiatria, 2005
In spite of significant advancements in imaging technology, monitoring, and microsurgical techniques, complete and safe removal of tentorial meningiomas remains a challenge for most neurosurgeons. Classifications of tentorial meningiomas are revised. The
